9 / 32 page v2.3 10/06/25 9 ES51950(5000counts) Dual Display/Cap 2. Operating Modes 2.1. Semi-auto calibration scheme ES51950 includes DMM & CLAMP_ON meter features in single chip. DMM manufacturers need the calibration process in production. The traditional solution needs the variable resistors for calibration by manual adjustment. ES51950 provide another calibration scheme and the variable resistors could be ignored. When ES51950 is at OFF-state, pull CAL_EN (pin 60) to V- to active the calibration scheme after re-power on. A digital controlled voltage output will be active from DAC_AO & DAC_VO. When semi-auto calibration scheme is active, use HOLD (or BKLIT) key to decrease voltage and use RANGE key to increase the voltage. Decrease the reference voltage means the counts on display will be increased. Increase the reference voltage means the counts on display will be decreased. The adjustment step is approximate one count. If coarse adjustment is required, push HOLD (or BKLIT) and RANGE larger than one second to speed up to approximate 30 counts per second. After calibration process is finished, push HOLD (or BKLIT) and RANGE (less than one second) simultaneously to save the digital control code to external EEPROM (24C02). RANGE Display Count Up Display Count Down Save Calibration data to EEPROM HOLD or BKLIT RANGE RANGE Display Count Up Save Calibration data to EEP HOLD + RANGE BKLIT + RANGE ROM RANGE Display Count Up Display Count Down Save Calibration data to EEPROM HOLD or BKLIT RANGE RANGE Display Count Up Save Calibration data to EEP HOLD + RANGE BKLIT + RANGE ROM |
